Scott Dixon swiped the pole from Will Power on the last lap to take the top spot Saturday for the Grand Prix of Baltimore.
Simon Pagenaud, Justin Wilson and Josef Newgarden round out the top five for the course that winds through the city streets.
Dixon won his second pole of the season. The Dixon-Power front row could make for an interesting start.
Dixon was penalized for inadvertently making contact with Power's Team Penske pit crew last Sunday. The mishap prompted IndyCar to install new rules involving drivers and the safety of pit crew members.
Power also spun Dixon in Saturday's practice.
Series points leader Helio Castroneves starts seventh.
